Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Window.scrollMaxX read-only property returns the
maximum number of pixels that the document can be scrolled horizontally.
xMax = window.scrollMaxX
xMaxis the number of pixels.
// Scroll to right edge of the page let maxX = window.scrollMaxX; window.scrollTo(maxX, 0);
Do not use this property to get the total document width, which is not equivalent to window.innerWidth + window.scrollMaxX,
window.innerWidth includes the width of any visible vertical
scrollbar, thus the result would exceed the total document width by the width of any
visible vertical scrollbar. Instead use
document.body.scrollWidth. See also
